BACKGROUND

Stress has a wide range of negative impacts on people, ranging from declines in real-time task performance to development of chronic health conditions. Despite the increasing availability of sensors and methods for detecting stress, there are very few existing stress intervention applications. Further, gaps still exist between what a person perceives as stress, and what is actually going on in the person's body.

DETAILED DESCRIPTION

Overview

This document describes techniques and apparatuses for implementing a mood-actuated device. In various embodiments, a controller receives mood information corresponding to a current mood of a user, or a group of users. The mood information can be received from one or more bio sensors, such as a heart rate monitor, an electrocardiography monitor, or a galvanic skin response monitor. Alternately, the mood information can be received as user-inputted mood information from a computing device that renders a user interface configured to enable the user to rate the user's current mood. The controller determines an emotional state of the user based on the mood information, and causes a mood-actuated device to react based on the emotional state of the user. In some embodiments, the mood-actuated device includes a flexible material that is configured to react by changing to a shape based on the emotional state of the user.

Example Environment

FIG. 1 is an illustration of an example environment 100 in which a mood-actuated device can be implemented. Environment 100 may include one or more bio sensors 102 and/or a mood-rating service 104. Both bio sensor 102 and mood-rating service 104 are configured to receive or sense indicators of a current mood, or emotional state, of a user, and provide mood information corresponding to the current mood or emotional state of the user to a controller 106. Environment 100 may include both bio sensor 102 and mood-rating service 104, only bio sensor 102, or only mood-rating service 104.

Bio sensor 102 can be any type of sensor configured to detect or sense indicators of a user's mood or emotional state. Bio sensor 102 can be implemented as a sensor that is configured to make physical contact with the user, such as a heart rate monitor that senses a user's heart rate, an electrocardiography monitor that senses the rate and regularity of a user's heartbeat, or a galvanic skin response monitor that senses the electrical conductance of the skin, to name just a few. Alternately, bio sensor 102 can be implemented as a sensor that does not make physical contact with the user, such as a camera or a microphone. For example, a camera sensor may be able to determine that a user is stressed based on the position of the user's eyebrows. Similarly, a microphone sensor may be able to determine that the user is stressed based on a tone of the user's voice. In some embodiments, bio sensor 102 can is configured to determine an emotional state of the user based on user interaction data received from social media, email, and/or chat applications.

After sensing the current mood of the user, bio sensor 102 provides mood information corresponding to the current mood of the user to controller 106 to enable the controller to determine an emotional state of the user. The mood information provided by bio sensor 102 may include indicators of the user's current mood or emotional state, such as changes in the user's skin temperature sensed by the galvanic skin response monitor, or changes in the user's heart rate sensed by the heart rate monitor. These indicators of the user's current mood or emotional state can then be used by controller 106 to determine the emotional state of the user. For example, an increase in the electrical conductance of a user's skin, as sensed by the galvanic skin response monitor, may be used by controller 106 to determine that the user is aroused or excited.

Mood-rating service 104 is configured to render a user interface on a display of a computing device that enables a user to rate the user's current mood or emotional state. For example, the user can rate the user's current emotional state as happy, sad, relaxed, or stressed. Mood-rating service 104 receives user-inputted data corresponding to the user's current mood via the user interface, and provides mood information corresponding to the current mood of the user to controller 106 to enable the controller to determine an emotional state of the user.

FIG. 2 illustrates a detailed example 200 of mood-rating service 104. In this example, mood-rating service 104 causes a computing device 202 to render a user interface 204 on a screen of the computing device. In this example, the screen is a touch-input display that is configured to receive touch-input from the user. Computing device 202 is illustrated as a mobile phone, but it is to be appreciated that computing device 202 may also be implemented as a tablet device, a communication device, an entertainment device, a gaming device, a navigation device, and/or other type of computing device. Computing device 202 can be implemented with various components, such as a processor and/or memory system to implement mood-rating service 104, as well as any number and combination of differing components as further described with reference to the example device shown in FIG. 9.

User interface 204 is configured to enable a user to rate the user's current mood. In various embodiments, the user interface includes a grid that enables the user to select between two opposite moods along a first axis, and two different opposite moods along a second axis that is perpendicular to the first axis. By way of example and not limitation, opposite moods can include happy and sad, calm and stressed, or relaxed and excited. In example 200, the user interface asks the user to respond to the question “how do you feel?” The user interface also includes a grid that enables the user to rate the user's current mood from negative valence (e.g., sad) to positive valence (e.g., happy) along a first axis (the x-axis in this example), and enables the user to rate the user's mood from excited to relaxed along a second axis (the y-axis in this example). In this example, the user has rated the user's current mood as mostly negative, and mostly excited. It is to be noted, of course, that this is just one example of a user interface that enables the user to rate the user's current mood. Mood-rating service 104 receives input indicating the current mood of the user, and provides mood information, based on the input, to controller 106 to enable the controller to determine an emotional state of the user.

Controller 106 receives mood information from bio sensor 102 and/or mood-rating service 104, and determines an emotional state of the user based at least in part on the mood information. Controller 106 can determine a variety of different emotional states of the user, such as the user being happy, sad, stressed, calm, excited, bored, or angry, to name just a few. In some embodiments, controller 106 may determine the emotional state of the user based on the received mood information and additional information, such as user history information or external information. For example, user history information corresponding to a specific user may enable controller 106 to more accurately determine the emotional state of the specific user. Additionally, external information, such as a current temperature, may be taken into account by controller 106 when determining the emotional state of the user. For example, information received from a galvanic skin response monitor indicating that the user's skin is hot may be less relevant if the temperature outside is over 90 degrees. As another example, information that the user's heart rate is high may be less relevant if external information is provided that indicates that the user is currently exercising.

After determining the emotional state of the user, controller 106 causes mood-actuated device 108 to react based on the emotional state of the user. Controller 106 can cause mood-actuated device 108 to react to correspond to a variety of different emotional states or moods of the user, including by way of example and not limitation, the user being happy, sad, stressed, calm, excited, bored, or angry. As described in more detail below, mood-actuated device 108 can be controlled to react to the emotional state of the user in a variety of different ways, such as by changing shapes, moving, making sounds, or lighting up, to name just a few.

In some embodiments, controller 106 causes mood-actuated device 108 to react to indicate the emotional state of the user. For example, if the emotional state of the user is determined to be “stressed”, controller 106 causes mood-actuated device 108 to reflect that the user is stressed. In other embodiments, mood-actuated device 108 is controlled to react to help change the emotional state of the user. For example, if the emotional state of the user is determined to be “stressed”, controller 106 causes mood-actuated device 108 to react in a way that may help to calm the user.

FIG. 3 illustrates a device 302 in which controller 106 may be embodied. Device 302 is illustrated with various non-limiting example devices: smartphone 302-1, laptop 302-2, television 302-3, desktop 302-4, and tablet 302-5. Device 302 includes processor(s) 304 and computer-readable media 306, which includes memory media 308 and storage media 310. Applications and/or an operating system (not shown) embodied as computer-readable instructions on computer-readable media 306 can be executed by processor(s) 304 to provide some or all of the functionalities described herein. Computer-readable media 306 also includes controller 106.

Device 302 also includes, or is in communication with, one or more bio sensors 102 and/or mood-rating service 104, and mood-actuated device 108. Bio sensor 102 and mood-rating service 104 are configured to capture mood information as discussed above, and may be separate or integral with device 302. For example, in some embodiments, bio sensors 102 and/or mood-rating service 104 may be located at device 302 along with controller 106. In other embodiments, bio sensors 102 and/or mood-rating service 104 may communicate with device 302 and controller 106 over a network. Mood-actuated device 108 may also be separate or integral with device 302. For example, in some embodiments, device 302 is implemented as part of mood-actuated device 108. In other embodiments, mood-actuated device 108 may communicate with device 302 and controller 106 over a network.

Device 302 may also include network interface(s) 312 for communicating data over wired, wireless, or optical networks. Data communicated over such networks may include mood information communicated from bio sensors 102 and/or mood-rating service 104 to controller 106, as well as control signals communicated between controller 106 and mood-actuated device 108. By way of example and not limitation, network interface 312 may communicate data over a local-area-network (LAN), a wireless local-area-network (WLAN), a personal-area-network (PAN), a wide-area-network (WAN), an intranet, the Internet, a peer-to-peer network, point-to-point network, a mesh network, and the like.

Mood-Actuated Device with Flexible Material

In various embodiments, mood-actuated device 108 includes a flexible material that is controlled to react to an emotional state of a user by changing shapes or textures. The flexible material can be any type of material or fabric that can move and/or change shapes, including felt, cloth, plastic, or metal, to name just a few. In some embodiments, the flexible material is configured to hang on a wall, but it is to be appreciated that the flexible material can be designed in any size and/or shape.

FIG. 4 illustrates a detailed example 400 of mood-actuated device 108 that includes a flexible material 402. In this example, flexible material 402 of mood-actuated device 108 is controlled by controller 106 to react to a change in the emotional state of the user by changing shapes from a flat shape illustrated at 108-a to a crumpled or enfolded shape illustrated at 108-b. In some embodiments, controller 106 causes flexible material 402 of mood-actuated device 108 to react to indicate the emotional state of the user. For example, the flat shape of flexible material 402 at 108-a may indicate a first emotional state of the user, and the crumpled shape of flexible material 402 at 108-b may indicate a second emotional state of the user.

In various embodiments, flexible material 402 is controlled to indicate the emotional state of the user by changing to a shape that visually mirrors the emotional state of the user. As described herein, a shape of the flexible material visually mirrors an emotional state when characteristics of the shape represent characteristics of the emotional state. At 108-a, for example, the relaxed shape of flexible material 402 may visually mirror that the emotional state of the user is calm. In contrast, the tight winding up of flexible material 402 at 108-b may visually mirror that the user is stressed. It is to be noted, however, that mood-actuated device 108 can be configured or mapped to change to any shape responsive to any emotional state of the user. For example, flexible material 402 could be controlled to change to the crumpled shape to indicate that the user is calm, and to change to the flat shape to indicate that the user is stressed.

In an embodiment, flexible material 402 of mood-actuated device 108 is configured to react to four quadrants of high or low arousal, and negative or positive valence. For example, as described above, if the user is in a state of low arousal, or calm, flexible material 402 can be controlled to react as illustrated at 108-a, and if the user is in a state of high arousal, or stressed, the flexible material can react as illustrated at 108-b. In addition to these examples, however, flexible material 402 can be controlled to react to visually mirror happiness if the user is happy, such as by being controlled to react with rapid movements of air pockets running through the flexible material. Alternately, if the user is sad, flexible material 402 can be controlled to react to visually mirror sadness, such as by being controlled to droop. It is to be noted, however, that mood-actuated device 108 can be configured to move in any direction or change into any shape to indicate any emotional state of the user.

By changing shapes, flexible material 402 notifies the user of the user's emotional state, and enables the user to alter this state through awareness. Consider, for example, that the user is unaware of being stressed. In response to the user's stressful state, flexible material 402 is controlled to change to the crumpled shape illustrated at 108-b. This crumpled shape may cause awareness by the user that the user is stressed which enables the user to act to reduce this stress level, such as by taking a few deep breaths or going for a walk. If the user is successful in relaxing, flexible material 402 notifies the user that the user has calmed down by changing back to the flat shape. It is to be appreciated, that noticing flexible material 402 react by changing back to the flat shape at 108-a may help to reassure the user that the user's stress level has been reduced.

In some embodiments, flexible material 402 is configured to change to a shape that can help change the emotional state of the user. The shapes that can help change the emotional state of the user can be based on studies that indicate that the user's emotional state is changed by watching or interacting with the shape of the flexible material. For example, if the emotional state of the user is “stressed”, controller 106 can cause flexible material 402 to react in a way that may help to calm the user such, as by causing the flexible material to slowly unfurl. Watching flexible material 402 slowly unfurl may help relax the user, thereby changing the user's emotional state from stressed to calm.

In non-limiting example 400, mood-actuated device 108 further includes wires 404, a microcontroller 406, and a power source 408. Flexible material 402 is interlaced with wires 404, which can be any type of wire that is configured to contract when heated, such as Nitinol wire. When wires 404 heat and contract, they cause flexible material 402 to react by crumpling as illustrated at 108-b. As wires 404 cool, they cause flexible material 402 to unfold and return to its original flat state as illustrated at 108-a. It is to be noted that other mechanisms may be implemented to cause the flexible material to react, such as servo motors.

Microcontroller 406 is configured to receive control signals from controller 106, and responsively cause power from power source 408 to be fed through wires 404 causing the wires to heat up and contract. For example, microcontroller 406 can turn on power source 408 for a predetermined amount of time to heat wires 404 thereby causing flexible material 402 to change to the crumpled shape at 108-b. Similarly, microcontroller 406 can turn off power source 408 to cool the wires thereby causing flexible material 402 to change back to the flat shape illustrated at 108-a. In some embodiments, mood-actuated device 108 may further include one or more hanging weights that are attached to the lower end of flexible material 402. These hanging weights help to pull flexible material 402 back to the flat shape as wires 404 cool.

Mood-Actuated Device with Mechanical Component

In various embodiments, mood-actuated device 108 includes a mechanical component that is controlled to react by moving based on the emotional state of the user. In some embodiments, the mood-actuated device is configured to be wearable by the user, and the mechanical component can notify the user, and in some cases other people, of the emotional state of the user. In these embodiments, bio sensor 102 may be implemented as part of mood-actuated device 108 to sense indicators of an emotional state of a user that is wearing the mood-actuated device. Alternately, bio sensor 102 may be implemented separate from mood-actuated device 108 and configured to communicate with mood-actuated device 108 via a wired or wireless connection.

FIG. 5 illustrates a detailed example 500 of a mood-actuated device 108 that includes a mechanical component 502. In this example, mood-actuated device is implemented as a robotic butterfly, and mechanical component 502 is implemented as mechanical wings of the robotic butterfly. Mechanical component 502 of mood-actuated device 108 is controlled by controller 106 to react by moving based on the emotional state of the user.

Controller 106 can vary the speed and/or the amount of movement of mechanical component 502 to indicate the emotional state of the user. For example, at 504 controller 106 causes the wings of the robotic butterfly to move a small distance, resulting in a “gentle hover”. At 506, controller 106 causes the wings of the robotic butterfly to move a greater distance than the distance moved at 504. At 508, controller 106 causes the wings of the robotic butterfly to move an even greater distance than the distance moved at 506, resulting in a “large flap” of the wings. In some embodiments, controller 106 causes mechanical component 502 of mood-actuated device 108 to react to indicate the emotional state of the user. For example, the movement of the wings of the robotic butterfly illustrated at 504 may indicate a first emotional state of the user, the movement of the wings at 506 may indicate a second emotional state of the user, and the movement of the wings at 508 may indicate a third emotional state of the user.

In various embodiments, mechanical component 502 is controlled to indicate the emotional state of the user by moving to visually mirror the emotional state of the user. As described herein, a movement of the mechanical component visually mirrors an emotional state when characteristics of the movement represent characteristics of the emotional state. For example, the gentle hover of the mechanical wings at 504 may visually mirror that the emotional state of the user is calm or relaxed. In contrast, the large flap of the wings at 508 may visually mirror that the user is stressed, excited, and/or nervous. In some cases, controller 106 can also control the speed at which mechanical component 502 moves. For example, controller 106 can control a duration of time for the full wingtip-to-wingtip contraction of the large flap at 508 to represent different emotional states of the user. To do so, controller 106 causes the wings to move slowly to increase the duration of time for the full wingtip-to-wingtip contraction, or to move quickly to decrease the duration of time for the full wingtip-to-wingtip contraction. It is to be noted that mood-actuated device 108 can be configured or mapped to any type of movement responsive to any emotional state of the user. For example, the wings could be controlled to move in the large flap of 508 to indicate that the user is calm, and to gently hover at 504 to indicate that the user is stressed.

Mechanical component 502 notifies the user of the user's emotional state through movement, and enables the user to alter this state through awareness. Consider, for example, that the user is unaware of being stressed. In response to the user's stressful state, the wings of the robotic butterfly are controlled to move in the large flap as illustrated at 508. This large flap may cause awareness by the user that the user is stressed, which enables the user to act to reduce this stress level, such as by taking a few deep breaths or going for a walk. If the user is successful in relaxing, the wings of the robotic butterfly notify the user that the user has calmed down by moving in the gentle hover as illustrated at 504. It is to be appreciated, that noticing the wings move in the gentle hover may help to reassure the user that the user's stress level has been reduced.

In some embodiments, mechanical component 502 is configured to move in a way that can help change the emotional state of the user. The movements that can help change the emotional state of the user can be based on studies that indicate that the user's emotional state is changed by watching or interacting with the movement of the mechanical component. For example, if the emotional state of the user is “stressed”, controller 106 can cause mechanical component 502 to react in a way that may help to calm the user such, as by causing the wings of the robotic butterfly to move in the gentle hover. Watching the wings of the mechanical butterfly move in the gentle hover may help relax the user, thereby changing the user's emotional state from stressed to calm.

In non-limiting example 500, mood-actuated device 108 further includes wires 510, a microcontroller 512, and a power source 514. In this example, the wings of the robotic butterfly are interlaced with wires 510 (not pictured), which can be any type of wire that is configured to contract when heated, such as Nitinol wire. When wires 510 are heated, they cause the wings of the robotic butterfly to close, and as wires 510 cool they cause the wings to open. Thus, microcontroller 512 causes the wings of the robotic butterfly to flap by causing power from power source 514 to be fed through wires 510 causing the wings to close, and reducing the power fed through wires 510 causing the wings to open. Microcontroller 512 can control the apex of the flap (e.g., how much the wings close) and/or the speed of the flap by modifying the voltage fed from power source 514 to wires 510. It is to be noted that other mechanisms may be implemented to cause the wings of the robotic butterfly to move, such as servo motors.

In some cases, the mechanical component can be designed so as to notify other people of the user's emotional state. For example, a mood-actuated device worn by a user could notify other people that the user is stressed by causing movement of the mechanical component. As an example, in a classroom environment, the mechanical component could notify the teacher whether or not each student is paying attention. In other embodiments, the mechanical component is configured to notify the user without notifying others of the user's emotional state. For example, the mechanical component can vibrate or move in a way that is noticeable to the user but is not noticeable by others.

Example Methods

FIG. 6 is a flow diagram depicting an example method 600 implemented by mood-rating service 104. Block 602 causes display of a user interface on a screen of a computing device that enables a user to rate a current mood of the user. For example, mood-rating service 104 causes a user interface 204 (FIG. 2) to be displayed on a screen of computing device 202 that enable a user to rate a current mood of the user.

Block 604 receives input indicating the current mood of the user, and block 606 provides mood information, based on the input, to a controller effective to cause a mood-actuated device to react based on the mood information. For example, mood-rating service 104 receives user input indicating the current mood of the user via user interface 204. Mood-rating service 104 then provides mood information, that includes the user input, to controller 106 effective to cause mood-actuated device 108 to react based on the mood information.

FIG. 7 is a flow diagram depicting an example method 700 of controlling mood-actuated device 108. Block 702 receives mood information corresponding to a current mood of a user. For example, controller 106 (FIG. 1) receives mood information corresponding to a current mood of the user from bio sensors 102 and/or mood-rating service 104.

Block 704 determines an emotional state of the user based on the mood information. For example, controller 106 determines an emotional state of the user based on the mood information received from bio sensors 102 and/or mood-rating service 104. Controller 106 can determine a variety of different emotional states of the user, such as the user being happy, sad, stressed, calm, excited, bored, or angry, to name just a few.

Block 706 causes a mood-actuated device to react based on the emotional state of the user. For example, controller 106 causes mood-actuated device 108 to react based on the emotional state of the user. In some cases, mood-actuated device 108 includes a flexible material 402 that is configured to react by changing to a shape that corresponds to the emotional state of the user. In other embodiments, mood-actuated device 108 includes a mechanical component 502 that is configured to react by moving based on the emotional state of the user.

FIG. 8 is a flow diagram depicting an example method 800 implemented by a mood-actuated device that includes a bio sensor. Block 802 senses indicators of an emotional state of a user. For example, bio sensor 102 (FIG. 1) can be implemented as part of a wearable mood-actuated device 108, such as the mechanical butterfly illustrated in FIG. 5. Bio sensor 102 can be any type of sensor configured to detect or sense indicators of a user's mood or emotional state. In this case, bio sensor 102 is implemented as a sensor that is configured to make physical contact with the user, such as a heart rate monitor, an electrocardiography monitor, or a galvanic skin response monitor.

Block 804 causes a mechanical component to move based on the emotional state of the user. For example, microcontroller 512 (FIG. 5) causes mechanical component 502 (illustrated as mechanical wings) to move based on the emotional state of the user sensed by bio sensor 102.
